[Bug 64321] Sony tx brightness keys doesn't work anymore in edgy

[EnolaGay]

Public bug reported:

Sony tx brightness keys doesn't work anymore in edgy. They work fine in Dapper and as I remember at first in edgy but now it doesn't work anymore.
The problem is that the relevant file /etc/acpi/sonybright.sh hasn't changed since dapper so it seems that the keys aren't recognized anymore or the daemon which calls sonybright.sh ignores them.
The TX series need /proc/acpi/sony/brightness to change brightness which works fine if I do it on my own.
